+**What it does**
+
+Velvet_ is a de novo genomic assembler specially designed for short read sequencing technologies, such as Solexa or 454, developed by Daniel Zerbino and Ewan Birney at the European Bioinformatics Institute (EMBL-EBI), near Cambridge, in the United Kingdom.
+
+Velvet currently takes in short read sequences, removes errors then produces high quality unique contigs. It then uses paired-end read and long read information, when available, to retrieve the repeated areas between contigs.
+
+Read the Velvet `documentation`__ for details on using the Velvet Assembler.
+
+.. _Velvet: http://www.ebi.ac.uk/~zerbino/velvet/
+
+.. __: http://www.ebi.ac.uk/~zerbino/velvet/Manual.pdf
+
+------
+
+**Input formats**
+
+Velvet can input sequence files in the following formats: fasta fastq fasta.gz fastq.gz eland gerald
+
+The input files are prepared for the velvet assembler using **velveth**.
+
+------
+
+**Outputs**
+
+**Contigs**
+
+The *contigs.fa* file.
+This fasta file contains the sequences of the contigs longer than 2k, where k is the word-length used in velveth. If you have specified a min contig length threshold, then the contigs shorter than that value are omitted.
+Note that the length and coverage information provided in the header of each contig should therefore be understood in k-mers and in k-mer coverage (cf. 5.1) respectively.
+The N's in the sequence correspond to gaps between scaffolded contigs. The number of N's corresponds to the estimated length of the gap. For reasons of compatibility with the archives, any gap shorter than 10bp is represented by a sequence of 10 N's.
+
+**Stats**
+
+The *stats.txt* file.
+This file is a simple tabbed-delimited description of the nodes. The column names are pretty much self-explanatory. Note however that node lengths are given in k-mers. To obtain the length in nucleotides of each node you simply need to add k - 1, where k is the word-length used in velveth.
+The in and out columns correspond to the number of arcs on the 5' and 3' ends of the contig respectively.
+The coverages in columns short1 cov, short1 Ocov, short2 cov, and short2 Ocov are provided in k-mer coverage (5.1).
+Also, the difference between # cov and # Ocov is the way these values are computed. In the first count, slightly divergent sequences are added to the coverage tally. However, in the second, stricter count, only the sequences which map perfectly onto the consensus sequence are taken into account.
+
+**LastGraph**
+
+The *LastGraph* file.
+This file describes in its entirety the graph produced by Velvet.
+
+**AMOS.afg**
+
+The *velvet_asm.afg* file.
+This file is mainly designed to be read by the open-source AMOS genome assembly package. Nonetheless, a number of programs are available to transform this kind of file into other assembly file formats (namely ACE, TIGR, Arachne and Celera). See http://amos.sourceforge.net/ for more information.
+The file describes all the contigs contained in the contigs.fa file (cf 4.2.1).
+
+------
+
+**Velvet parameter list**
+
+This is a list of implemented Velvetg options::
+
+  Standard options:
+        -cov_cutoff  floating-point|auto : removal of low coverage nodes AFTER tour bus or allow the system to infer it
+                (default: no removal)
+        -ins_length  integer             : expected distance between two paired end reads (default: no read pairing)
+        -read_trkg  yes|no               : tracking of short read positions in assembly (default: no tracking)
+        -min_contig_lgth  integer        : minimum contig length exported to contigs.fa file (default: hash length * 2)
+        -amos_file  yes|no               : export assembly to AMOS file (default: no export)
+        -exp_cov  floating point|auto    : expected coverage of unique regions or allow the system to infer it
+                (default: no long or paired-end read resolution)
+
+  Advanced options:
+        -ins_length2  integer            : expected distance between two paired-end reads in the second short-read dataset (default: no read pairing)
+        -ins_length_long  integer        : expected distance between two long paired-end reads (default: no read pairing)
+        -ins_length*_sd  integer         : est. standard deviation of respective dataset (default: 10% of corresponding length)
+                [replace '*' by nothing, '2' or '_long' as necessary]
+        -scaffolding  yes|no             : scaffolding of contigs used paired end information (default: on)
+        -max_branch_length  integer      : maximum length in base pair of bubble (default: 100)
+        -max_divergence  floating-point  : maximum divergence rate between two branches in a bubble (default: 0.2)
+        -max_gap_count  integer          : maximum number of gaps allowed in the alignment of the two branches of a bubble (default: 3)
+        -min_pair_count  integer         : minimum number of paired end connections to justify the scaffolding of two long contigs (default: 10)
+        -max_coverage  floating point    : removal of high coverage nodes AFTER tour bus (default: no removal)
+        -long_mult_cutoff  int           : minimum number of long reads required to merge contigs (default: 2)
+        -unused_reads  yes|no            : export unused reads in UnusedReads.fa file (default: no)
+
+  Output:
+        directory/contigs.fa             : fasta file of contigs longer than twice hash length
+        directory/stats.txt              : stats file (tab-spaced) useful for determining appropriate coverage cutoff
+        directory/LastGraph              : special formatted file with all the information on the final graph
+        directory/velvet_asm.afg         : (if requested) AMOS compatible assembly file
